[c-nsp] ASR 1002-F NetFlow

[Henry-Nicolas Tourneur]

Hello,

 

We are using NetFlow v9 on 2 edge BGP routers (ASR 1002-F) but that works
only partially.

Indeed, approximatevily 50% of destination and source AS are marked as AS0.

 

I often read this is due to not having a full BGP router or not having CEF
enabled, which isn't our case.

 

Here's our config:

 

interface GigabitEthernet0/0/0

 ip flow ingress

 ip flow egress

 

ip flow-export source Loopback0

ip flow-export version 9 origin-as

ip flow-export destination IP_SERVER 3000

 

I also tried with version 5, ip route-cache flow, ip flow-egress
input-interface, nothing works.

In the config Gi0/0/0 is our DIA interface.

 

Do you have any idea why this happens?

 

Thanks for your help,

 

Henry-Nicolas Tourneur.
